GUIDE-FRAME FOR SLIDING WINDOW-VBLlNDS.

SPECIFICATION forming part of Letters Patent No. 362,854, dated May 10,1887.

Application filed February 23, 1886. Serial No. 192,779.

To aZZ whom, it may concern.-

Be it known that I, GEORGE POPPERT, of Milwaukee, in the county ofMilwaukee, and in the State of Visconsin, have invented certain new anduseful Improvements in Guide- Frames for Sliding XVindow-Blinds; and Ido hereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates to guideframes for sliding window-blinds; and itconsists in certain peculiarities of construction, as will be fully setforth hereinafter.

In the drawings, Figure l is a front elevation of a windowcasing withIny invention applied thereto. Fig. 2 is a transverse horizontalsection, and Fig. 3 is a vertical section at right angles to thesectiou-line of Fig. 2, through the guide-frame and adjacent parts; andFig. 4t is a perspective view of one of the springs.

A represents one of the jambs or side boards of the window-easing, and aa are the ornamental strips concealing thel edges of the same, while B Bdesignate the casings of the guideframes C. These easiugs I3 are likeboxes, open at one side and at the top and bottom ends, and are. placedvertically against the side boards, A, and strips a. of the windowcasings, and secured thereto by screws b b, as shown, or otherwise. asmost convenient.

The guide-frames C consist of vertical strips, of a width to enable themto just fit inside the box-like easings B. On their inner or concealedsides these frames C are preferably smooth, and are adapted to bearagainst the springs D D, which are secured, preferably, to the casiugsIS, (though obviously the said springs may be secured to the inner sideof the frames C instead.) The outer side of the frames C is providedwith a series of beads, c c c, (three in the illustration given,) whilebetween each bead the surface of the frame is rounded, so as to presentno sharp corners or angles for the lodgmcnt of dirt.

The edges of the Stiles c ofthe sliding blinds (No model.)

E are furrowed out to forni coves e', corresponding to the shape of thesaid beads c, on which the blind -stiles slide. Each blind slides freelyup and down on the beads of the guideframe, and is held in any preferredposition in which it may be left by the expansive force of the springs DD, which are always concealed from sight, and hence are kept clean andin order without trouble, and at the same time will always yieldsufficiently,v to enable any blind to be removed at any time, ifdesired, and to be readily replaced.

In order to prevent the frames G from being sprung away lfrom thecasing,screws b b' are passed through smooth holes in the casing from the rearinto the adjacent side of the said frames C, and holes or pockets a aare formed in the jambs A to receive the heads ofthe said screws b whenthe frames are pressed into tbeir boxes or easings B against the forceof the springs D. Inasmuch as the casings B and frames C are thus unitedtogether, in order to secu re the casing B to the jamb A, holes bt b2are provided in the frames C to admit ofthe passage of the screws b anda screw-driver to drive them to place.

Having thus described my invention, what] claim as new, and desire tosecure by Letters Patent, is-

In a guide-frame for sliding wiiulow-blinds, the combination of suitableboxes or casings, movable vertical guide-strips, springs interposedbetweeu the said parts, and screws passed through holes in the casingand secured to the adjacent surface ofthe guide-strip, substantially asset forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.

GEORGE POPPER'I.
